[Surgical therapy for WPW syndrome combined with paroxysmal atrial tachycardia].
A 47-years old man presented with life-threatening paroxysmal supraventricular tachycardia. Electrophysiological study revealed both paroxysmal atrial tachycardia and atrioventricular reentrant tachycardia. The earliest site of activation during paroxysmal atrial tachycardia was located on the cranial portion of the left atrium and just behind the aorta. The atrioventricular accessory passway was located at the posterolateral wall of the left ventricle. Cryosurgical ablation was performed to the cranial portion of the left atrium and the accessory passway was interrupted from inside of the left atrium under the cardiopulmonary bypass. In the postoperative electrophysiological study, neither atrial tachycardia nor atrioventricular reentrant tachycardias was inducible. Since then he has never experienced tachycardia attack for one year.
